The following should partially helps: It solves the segfault for
z(:) = [ x, y ]
and does a deep copy.
TODO:
- I miss a freeing of the components of the LHS, there is currently just a
malloc, cf.
- Realloc on assign does not work properly:
* Valgrind shows: "Conditional jump or move depends on uninitialised value"
* Values print Ok, but afterwards it segfaults
- with reshape, the values are still wrong.
